Boos/ TER 'Moron-Tauck CONSTRUCTION.' f

Application inea July 9,

y This invention relates to truck construction for locomotive boostermotors' and is y'. lparticularly concerned with the ,provisionl of an improved means for lubricating the journals of a 'four-wheeled-truck equipped with a booster which lis adapted to drive one of Vtheaades directly and the other one thru `the intermediation of connecting rods `and suitabler cranks atthe ends of the axles.

Trucks yof the foregoing description are commonly `employed where :the boosteris to be applied to the locomotive.;tender*and my invention will be better' understood if some of the problems involved in this type of V equipment are first enumerated.' Y

As is now wellunderstood H in this art booster motors are arranged to have a driving connection to'an axle at a point intermediate the wheels and when applied to a truck having two or more axles it is desirable to connect theaxle which is ydirectly driven by the booster motor to the other axle or axles by means of suitable cranks at the ends of the axles together with the necessary connecting rods. This arrangement, course, makes it necessary that the axle boxes Y i be capable of absorbing the driving power.

In other words they actually become small driving boxes similar to those which are used on the main drivers of the locomotive. This immediately imposes the necessity of thoroughand adequate lubrication'and, as

stated, my invention .relates to a truck con-v struction which embodies the foregoing arrangement of parts together with the'necessary means for lubricating the journal box.

The objects of' my invention can be specifically statedl as involving the provision of `a suitable construction in which the lubrieating cellar is removable outwardly of the axle. How this together with such othei` objects as may appear hereinafter or are incident to my invention are attained will-appear in connection with the following description of the accompanying drawings in which Y l Fig. 1 is a side elevation of .a truck em, bodying my improvements;

` Fig. 2 is a half plan view of the truck;

Fig. 3 is an enlarged side elevation taken at the end of an axle with many of the parts omitted for the sake of bringing out certain details of the invention;

Figs. f4 and 5 are'cro'ss and longitudinal sections respectively of the removable cellar;`an'd Y y 1 F ig. 6 isa fragmentary perspective view looking toward the end of an'ax'le to illustrate the manner in which the lubricating cellaris removed. i f f hetruck kcomprises the frame 1 having the axles 2. and 3, the latter of ywhich is directly driven intermediate its wheels 4 by means of the booster motor 5. The details of Vthe driving connection between the booster motor and the axle 3 are not thought to be necessary to this disclosure inasmuch as they form no; Vpart of the present invention.v V

' :The load. which the truck is designed to. carry is receivedl at the center plate 6 and distributedto the axles thru the medium Vof suitable springs 7 and distributing vlevers 8 the details ofA which need not be yelaborated upon since they form no part ofthe present invention. Suiiice it to say that the levers are so formed as to-carry the weight to the top of the axle boxes 9 which are mounted in the usual manner in the pedestal jaws 10. y

At each axle-end there-is a crank llfand the adjacent cranks at each side are con-v nected by means of a connecting rod 12 whichk acts thru `the crank pins 13. The crank is keyed to the axle by means of the keys 14. i y i.

For a .purpose which will `appear Vthe counterweights for thecranks and the connecting rods are located on the wheels 4 invcev stead ofon the cranks themselves as is customary in constructions of thisk type.r

These counterweights l5 appear most clearly in Fig. 3.

It willjbe noted that I have arranged'the l axle boxes 9 between the cranks 11 vand-the lar and cooperating holes QOin the box sides. l The cellar is a simple open ended one which is readily removable outwardly upon removalof ythe pins 18 when the cranks 11 are in their upper position. As willv be evident this could not be arranged for if thev Vhole 22 drilled thru a side of the box. vThis permits of oiling of the lubricator at the end of ,each trip Vwithout the necessity of re-V moving the cellar the latter operation taking two or'rthree weeks.. the box removable outwardly below the crank when the latter is in its upper position,"and an oiler extending rthru a box side y place at intervals of say Iclaim:-- f Y Vl. In truck constructionV the combination of an axle, a wheel, a crank atV the endof the axle, a journal box between the wheel and the crank, and a` lubricating cellar in the-inbox,V Vremovable outwardly below the crank fwhen vpairfoi' axles with their wheels, a booster Y, the latteris in its upper position.

In truck construction tlief combination of an axle, a wheel, acrank at theV end of the axle, a counterweight on the wheel, an inverted Ushaped Laxle box [between the wheel and the crank, ya 'lubricating cellar in for oiling` the Vlubricator withoutremova thereof; y l

5. The combination of a truck frame, a

motorjhaving a driving `connection to oneof said axles between its wheels, a crank at each axle end, a connecting rod between adjacent cranks, a,l counterweight on each wheel,

In testimony whereof, I vhave hereunto signed my name.
